The announcement was made Friday morning in downtown Los Angeles. The three California tech companies will provide advanced information and communication technologies such as chipsets for Huawei’s networks, solutions and mobile phones.

A company spokesman declined to break out the amount of each individual contract.

Charles Ding, a corporate senior vice president at Huawei, said the move underscored the company’s commitment to the U.S. market and “demonstrates Huawei isn’t a competitor to American companies; Huawei is a partner to American companies.”

The 25-year-old tech firm based in Shenzhen, China, has evolved into the world’s second-largest provider of telecommunications infrastructure and has been growing into a more global company.

Huawei began operations in the U.S. in 2001 and has since partnered with 280 U.S. tech firms. Huawei’s U.S. headquarters is in Plano, Texas.
